Disbelievers may live well on sinful Earth. Creator gave human
'beings' plenty of freedom.
The mortals will learn the truth (primarily about themselves) in the hereafter...
That I am sure of.
Faithful moderate muslims will never abandon their old faith to become an arrogant self-righteous non-believer like she is an example of.
And if some would, they'll eventually end up a hedonist confused bunch just like modern Westerners (and that includes you and me
)
